Passing parameters to a SQL Query (Google BigQuery)

I am trying to pass query parameters to a sql query. Basically the connection is ODBC (Google Bigquery). The query runs and returns data perfectly when there are no parameter references. However when I add a parameter reference, It returns a table with Blank data

OK SQL (Returns table with records):

Select *

from xxxx

Where

Location_Country IN ('South Africa')

Limit 1000

NOK SQL (Returns table with 0 records):

Select *

from xxxx

Where

Location_Country IN ("&Country&")

Limit 1000

Country is a Parameter (Text Type) created in Power Query. Refer to attached Pic
